Elizabeth A. Thiele, MD, PhD
Neurologist

Dr. Elizabeth Thiele: TSC is caused by a mutation in one of two genes. So it is a genetic disorder, meaning it results from a change or a mutation in DNA. And it can occur spontaneously, meaning there is no one else in the family, including the parents, that have the mutation. Or it can be passed on through a family.
